I have created a Parameter with GENERATESERIES in order to filter amounts of two fact tables by using increments:
GENERATESERIES(MIN(MINX(one_fact,one_fact[amount]),MINX(two_fact,two_fact[amount])), MAX(MAXX(one_fact,one_fact[amount]),MAXX(two_fact,two_fact[amount])), 250000)
But the Slicer only shows the increment for "Single Value" not for "Greater then or equal to", as i need it:


Any ideas how to fix that?
I don't think you can, or I don't think the slicer supports increments when the slider is used (except for Single Value).
However, suggest you keep it as Single Value and handle the
greater than or equal tovia dax expression in Measures.
